CREST-M Math and Robotics Curriculum
Today’s science, technology, engineering, and mathematics (STEM) workforce is no more diverse than it was in 2001. With a $245,000, two-year grant from the Bayer Fund, Maryville University’s Center for Access and Achievement is working to help close that gap by engaging students who are traditionally underrepresented in STEM.
This initiative focuses on:
-
Young females
-
Minority students
-
Students from low-income communities
Through a series of 3 STEM units, this program integrates mathematics aligned with Common Core State Standards and hands-on learning with LEGO® WeDo 2.0 robotics kits. The project focused on developing elementary math skills using robotics and storytelling to be engaging for students from backgrounds traditionally underrepresented in STEM fields and to be appropriate for all ability levels, including the gifted.
Our mixed-methods study, published in Roeper Review, evaluated one CREST-M unit: The Tale of the Monarchs. The unit is aligned with the Common Core State Standards for Mathematics (CCSS-M), focusing on fourth- and fifth-grade fractions while incorporating all aspects of STEM.
Program Design and Impact
The unit is designed to be interactive and engaging, giving students hands-on experience with STEM concepts. Students participate in:
-
An engineering design loop to create and program robots using LEGO® WeDo 2.0
-
A problem-based learning (PBL) investigation where they apply the scientific method to design and conduct experiments
These activities are connected through a comprehensive storyline in which diverse characters solve real-world problems using STEM skills.
The curriculum was evaluated using multiple measures, including a CCSS-M aligned pre- and post-assessment on students’ understanding of fractions, the Cognitive Abilities Test Screening Form 7 (CogAT 7), and a Draw-a-Scientist pre- and post-assessment. Results showed:
-
Significant improvement in math achievement (Cohen’s d = 0.72)
-
Consistent gains across multiple ability levels, including high-ability students
-
Positive outcomes across gender, race, and socioeconomic groups
In addition, students’ perceptions of scientists became more complex and less stereotypical after completing the program, indicating a stronger and more accurate understanding of careers in science.
